I use the vc mode stuff with CVS inside XEmacs all the time. I typically compare the current file with the latest revision using ediff-revision. When you quit it leaves point in the 'a' window. I understand the consistency in the various ediff commands all operating that way, but I can't tell you how many times I have failed to remember to change buffers after a comparision and merrily began editing the file ediff-revision checked out of CVS. I think it would be extremely helpful if ediff-revision always made the 'a' buffer read-only to avoid this problem. In fact, if the user asks to compare two different versions from the repository, I think both buffers should be made read-only. I modified ediff-vc-internal in my init.el file. This patch seems to do what I want: *** /tmp/skipm/ediff-vers.el Tue Mar 20 15:39:14 2007 --- /tmp/skipm/init.el Tue Mar 20 15:39:14 2007 *************** *** 11,22 **** (save-excursion (vc-version-other-window rev1) (setq rev1buf (current-buffer) ! file1 (buffer-file-name))) (save-excursion (or (string= rev2 "") ; use current buffer (vc-version-other-window rev2)) (setq rev2buf (current-buffer) ! file2 (buffer-file-name))) (setq startup-hooks (cons `(lambda () (delete-file ,file1) --- 11,25 ---- (save-excursion (vc-version-other-window rev1) (setq rev1buf (current-buffer) ! file1 (buffer-file-name)) !
